If you're using FIPS county codes, they're 2-digit state + 3-digit county.
gen int fipscnty = (1000 * state) + county
I'm assuming you want this numeric. You can also create a string code
like this:
gen str5 fipscnty = string(state, "%02.0f") + string(county, "%03.0f")
The "%0#.#f" format creates leading 0s as needed.

Dear Statalist users:
I would like to combine two variables in one:
The first variable represents the state: e.g. CA (California) or AZ
(Arizona).
The second variable represents the countiy and includes numbers: 01,...
The combination of both variables finally states from which county the
individual is from, e.g. CA 01 is county Alameda, AZ 01 is county
Apache, etc.
Does anyone know a trick how to combine both variables so that it
identifies uniquely the county where the person is from?
Thanks a lot!!
Johannes
